Hello Mathworkers,

I am littel bit confused about the Detection Rate equation I found to formal for it and not sure which one is correct and if both are correct whene to use each one

Detection Rate = TP / (TP+FP)

Detection Rate = TP / (TP+FN)

if any one could explain this to me please

Both are true, but represents the two different terms

True Positive Rate: TP / (TP+FN);

True Negative Rate: TP / (TP+FP);

The broad concepts are same, but the illustration may different based on application. see here

Still you have no clue, let me know.
